Some excellent research from Chris, canvassing opinions on whether there’s a difference between web “apps” and web “sites”. His conclusion:

Almost none of the points above ring true for me. All I see are exceptions and gray area.

If nothing else, the fact that none of the proposed distinctions agree with one another show how pointless the phrase “web app” is—if people have completely differing ideas on what a phrase means, it is completely useless in furthering discussion …the very definition of a buzzword.

This leads me to think perhaps the “web app” moniker (certainly the newer of the two) is simply just a fashionable term. We like the sound of it, so we use it, regardless if it truly means anything.

But all of this is, I think, missing the more important point: why? Why would you want to separate the cornucopia of the web into two simplistic buckets? What purpose does it serve? That’s the question that really needs be answered.

If we could pin down a super accurate definition that we agreed on, even then it might not be particularly useful. And since we can’t, I argue it’s even less useful.

The most accurate (and damning) definition of a “web app” that I’ve heard so far is: a web site that requires JavaScript to work.
